If you need to switch return lines as well as feed, and control the gauge circuit, this will do all of it. You can add a second one and control 3 tanks all with the rotation of a single rotary switch and a bit of wiring knowledge. My setup works perfect. No floor lever and a factory looking knob. 3 port if no return line, 6 port if you use the return lines.
